Best lithium battery, but don't think they outperform for the price. Yes they hold a charge for years when not in use, so they're good in low power consumption products, but are not worth the money compared to alkaline when using in a flashlight and measuring hours of light time vs. cost of battery. Triple the price does not equate to triple the hours of use, but they'll hold a charge and do not deteriorate in voltage over long periods of time when not in use. Good for storage, emergencies, use in a flashlight that sits in a car unused for a long time. But if you're burning up batteries with high use in toys and daily use, go with Alkaline. Read more

I use the Energizer Ultimate Lithium AA batteries throughout my Airbnb to keep essential devices — from smart locks to remotes — running smoothly. They last significantly longer than standard batteries, which means fewer replacements and more peace of mind. Guests benefit from uninterrupted convenience, and I appreciate the dependable performance. Long-lasting, low-maintenance, and a smart investment for any hosting setup. Read more

Works great for our outdoor security cameras. Batteries are long lasting. We tried other brands, but these hold up the best, and we don’t have to change batteries as often. It was a noticeable difference when we switched to using these. Read more
